Trial Phases

Phase 1, Phase 2, Phase 3

Clinical trials often recruit healthy volunteers for Phase 1 pharmacokinetic and safety studies, vaccine immunogenicity assessments, and normal physiological reference studies. These trials are essential for establishing safe dose ranges and understanding how drugs behave in the absence of disease before testing in patient populations.

Healthy volunteer studies include first-in-human drug trials, vaccine efficacy (flu, RSV, COVID-19, malaria), microbiome intervention studies, exercise physiology research, and device safety assessments. Compensation is often provided; eligibility typically requires no significant medical history and a negative drug screen.

Healthy volunteer trials require participants to be in good general health with no significant medications. Many exclude smokers, pregnant individuals, and those with recent prior trial participation.

Frequently Asked Questions — healthy Clinical Trials

How many clinical trials are currently recruiting for healthy?

ClinicalMetric currently tracks 71 actively recruiting clinical trials for healthy, sourced in real time from ClinicalTrials.gov. The total number of registered studies—including those not yet enrolling or in active follow-up—is 71. Trial availability changes daily as new studies open enrollment and existing ones reach capacity.

What trial phases are available for healthy?

healthy research spans Phase 1 (16 trials), Phase 2 (2 trials), Phase 3 (2 trials), Phase 4 (1 trial). Phase 1 studies evaluate safety and dosing in small groups, Phase 2 studies assess preliminary efficacy in 100–300 participants, and Phase 3 trials compare the new treatment against the standard of care in 300–3,000+ patients. Phase 4 post-approval studies monitor long-term outcomes in real-world populations.

How do I find out if I qualify for a healthy clinical trial?

Eligibility criteria for healthy trials vary by study and typically specify age range, disease stage or severity, prior treatment history, and specific diagnostic or laboratory parameters. Each listing on ClinicalMetric links to the full protocol on ClinicalTrials.gov, where inclusion and exclusion criteria are documented. Contact the sponsoring site's research coordinator directly to confirm your eligibility—your treating physician or specialist can also help identify the most appropriate trial based on your medical history and current treatment status.
